Problems solved by technology

[0003] The technical problem solved by the present invention is to design a special grinding head for the plane secondary enveloping toroidal worm. It does not affect the change of the height of the grinding wheel, reduces the adjustment of the height of the grinding wheel, and has a high degree of automation in the compensation and dressing of the grinding wheel, which overcomes the shortcomings of the existing grinding head, such as low precision, poor rigidity, troublesome adjustment, and low automation in the compensation and dressing of the grinding wheel

Abstract

The invention relates to a grinding head dedicated to a planar double-enveloping worm. A cross-shaped sliding table is provided with a grinding head stand column, a front flange and a rear flange are arranged at the two ends of a shaft sleeve; an adjustment worm gear arranged on the shaft sleeve is meshed with an adjustment worm arranged on the grinding head stand column; a compensation guide rail strip arranged at the inner end face of a grinding tool is matched with the compensation guide rail strip arranged on the outer end face of the front flange; a grinding wheel is arranged on the principal axis of the grinding tool and the working surface of the grinding wheel coincides with the central axis of the shaft sleeve; the grinding head stand column is internally provided with a clamp mechanism, the outer end face of the rear flange is provided with a TV, and a belt pulley fixed on the principal axis of the TV is connected with the belt pulley fixed on the principal axis of the grinding tool through the belt. In the invention, no matter how the operating angle of the grinding wheel changes, the working surface of the grinding wheel always coincides with a grinding wheel inclination angle adjustment shaft, the adjustment of the angle of the grinding wheel does not affect the height change of the grinding wheel, the automation degree of grinding wheel compensation and finishing is high, and the structure of the complete machine features in delicate design, convenient adjustment and stable and reliable performance.

Description

technical field [0001] The invention relates to a special grinding head for a plane secondary enveloping toroidal worm, and belongs to the technical field of manufacturing equipment for a plane secondary enveloping toroidal worm. Background technique [0002] The special grinding head for plane quadratic enveloping toroidal worm (referred to as "toroidal worm") is a key component of toroidal worm machine tools. At present, all the toroidal worm machine tools in China, whether they are ordinary or numerically controlled, put the turning and grinding of the toroidal worm on the same machine tool. Install the turning tool holder when turning, and remove the turning tool holder when grinding, and replace it with a special grinding head. Due to the complexity of the machining process of the plane quadratic enveloping toroidal worm, it is necessary to manually adjust the four parameters of the grinding wheel, the working angle, the working height, the turning radius of the grindi...
